- Synopsis
- This is an image of a Common horsetail: Equisetum arvense.There is a locator dot shown, which will be at the top left of the page when the image is the correct way up.The horsetail's rhizome (underground stem) is at the bottom of the page. There are thin roots branching down from it, and on its right four small, round tubers.Curving up from the left of the rhizome is a brown fertile stem. Like the rest of the plant there are several nodes along its length. At the top of this stem is a strobilus, a structure carrying the sporangia, which produce spores. Here they are represented by many small dots.To the right of the fertile stem is a young shoot and branching off to the right of this, going vertically up the page is a non-fertile green stem. This has branches off to the left and right of the stem. On a real plant there would be many more branches, up to ten in each group, but for clarity only four in each group have been shown here.The horsetail is a primitive plant and does not have flowers or seeds. It can grow up to 30 centimetres high.
